Much has been made of the Thailand setting, with Ed Helms previously claiming that they went to "hell and back" shooting the sequel in the country. Part of Helms' assessment may have been from his many bouts of food-related illness, which were also suffered by many of the cast and crew. "It does something to your mind when you get that sick," Helms told EW. "You go to a scared, dark place."

The new photos show only a taste of the insanity that Helms, Galifianakis, and Bradley Cooper experience as they try to find the soon-to-be brother-in-law of Helms' character Stu (Mason Lee). Not lost this time around is Justin Bartha, though he doesn't appear in many of the new photos.

Mr. Chow (Ken Jeong) returns for the sequel, and may be the key reason they don't remember much from the night before. While there's no tiger, there is a drug-dealing monkey and, instead of a baby, the trio seems to have come across an elderly monk.
